Interpenetrating Polymer Networks as a Route to Tunable Multi-responsive Biomaterials: Development of Novel Concepts

Novel concepts are proposed for interpenetrating polymer networks (IPNs) that can be used in biomaterials responsive to multiple types of environmental stimuli. The IPNs can be a route to the tunable biomaterials whose chemical structure and/or morphology can be adjusted to the type of task to be performed. The significance of utilizing new types of processes in polymer chemistry such as the Suzuki polycondensation and living/controlled radical polymerizations to the possibility of extending/modifying component networks in the IPNs and fine-tuning their properties is emphasized. Incorporation of nanofillers into IPNs and application of monomers other than traditional alkylacrylamides as a way to enhance versatility of IPNs are also considered.
